Crystalline silicon solar cell with through-hole passivation layer
A recently granted patent (Publication Number: US11961930B2) discloses a novel design for a crystalline silicon solar cell. The invention features a crystalline silicon substrate with a passivation layer that includes a through hole, a carrier collection layer, and an electrode in contact with the carrier collection layer. The unique aspect of this solar cell design is the configuration where the carrier collection layer contacts the substrate through the through hole in the passivation layer. Additionally, the electrode has a portion that aligns with the through hole, located inside it, with a specific distance from the substrate. The patent also includes variations such as an anti-reflection layer on the carrier collection layer and a second passivation layer with a second carrier collection layer on the opposite side of the substrate.
Furthermore, the patent extends to a photovoltaic module incorporating a string of these crystalline silicon solar cells, showcasing their potential for larger-scale applications. The design variations in the patent cater to different conductivity types for carrier collection layers and doped layers, enhancing the versatility of the solar cell technology. The presence of through holes in the passivation layers and the specific electrode configurations highlight the innovative approach to improving the efficiency and performance of crystalline silicon solar cells. Overall, the patent offers a comprehensive insight into the advancements in solar cell technology, particularly focusing on crystalline silicon-based designs with unique features aimed at enhancing energy conversion capabilities.
